AMD Radeon R9 285 Review: Feat. Sapphire R9 285 Dual-X OC
by Ryan Smith on September 10, 2014 2:00 PM ESTMetro: Last Light
As always, kicking off our look at performance is 4A Games’ latest entry in their Metro series of subterranean shooters, Metro: Last Light. The original Metro: 2033 was a graphically punishing game for its time and Metro: Last Light is in its own right too. On the other hand it scales well with resolution and quality settings, so it’s still playable on lower end hardware.
Metro, though perhaps a bit optimistic, does a decent job of setting the tone for this review. Right off the bat we can see that the R9 285 and R9 280 are performing closely to each other, with the newer R9 285 leading by 5-9%. On the whole this is greater than the average, but it’s otherwise a solid example of where the R9 285 fits into AMD’s world. In terms of design it is a lateral, but the same is also true from the resulting performance. It is not meant to – nor generally will it – perform differently from the R9 280 it replaces. R9 285 is in a nutshell an R9 280 with more features.
What this also means though is that AMD generally has the $250 price segment to themselves. In the case of Metro they have little trouble outperforming the GTX 760, and at times come close to the more expensive GTX 770. This is why Metro is a bit optimistic, since on the whole R9 285 isn’t quite enough to catch up to GTX 770.

The point is that Tonga is NOT a rebrand. It's a brand-new chip, AMD themselves call it the 3rd generation of GCN. Making a new chip costs AMD a sgnificant amount of money, that's why they haven't bothered yet to update Pitcairn to at least 2nd gen GCN (1.1). And I'm totally fine with that. It's also OK for nVidia to use GK104 for GTX760. What's not OK - from my point of view - is AMD investing into this new chip Tonga and hardly getting any real world benefit over the 3 year old Tahiti designs. If nVidia introduces a Maxwell which performs and costs them just the same as the previous Kepler, I'll call them out for this as well. But this is pretty much excluded, from what we've seen so far."And I highly doubt the 285 is 'all amd has'."
It's their 3rd gen GCN architecture, as they say themselves. There's going to be a bigger chip using this architecture, but apart from that I doubt we'll see anything from AMD in the next year which is not yet in Tonga.

The one nice thing about the 285 is it will have resale value that has been lost on the 280-290 series thanks in large part to bit mining. There's a good chance that most won't feel that the 285 (and future incarnations) were run into the ground like the earlier ones were.Frenetic Pony - Wednesday, September 10, 2014 - link
Nah, what's interesting is that Maxwell may not be worth "responding" too. It's an almost totally mobile focused design, one that's not even totally out yet. If these benchmarks hold true then it's very exciting for AMD's upcoming high end. Nvidia may end up with a 512bit bus as well, but AMD's bandwidth optimizations will mean a similarly specced card of their's will still handily beat anything NVIDIA has in terms of resolution scaling.Heck it may even be enough to get a single GPU capable of running games at 4k at a reasonable fps. And that would be awesome. Maxwell might be good for Nvidia's mobile business, but I doubt it's going to help them take back the top spot for high end stuff from AMD.

UVD always supported vc-1. The first version supported full decode of h264 and vc-1. You are thinking of nvidia, who didn't have full hardware decode on a real desktop part until fermi.mindbomb - Wednesday, September 10, 2014 - link
Not that it matters really. It stopped being relevant when hd-dvd lost to bluray.Navvie - Thursday, September 11, 2014 - link
A lot of blu-rays have vc-1 content.nathanddrews - Thursday, September 11, 2014 - link
Blu-ray.com has a database that you can search by codec. VC-1 is very much alive and thriving.Ryan Smith - Wednesday, September 10, 2014 - link
According to my DXVA logs, the 280 did not support VC-1/WMV9. That is what I'm basing that on.mindbomb - Wednesday, September 10, 2014 - link
I think your logs are referring to the nvidia gtx 280, which did not support full vc-1 decode. AMD had it since the radeon 2600xt, which is ancient.NikosD - Saturday, September 13, 2014 - link
True.One of the main advantages of first generation UVD (ATI Radeon HD2000 series) over Nvidia, was the full DXVA VLD support of both 1080p H.264 L4.1 (BluRay spec) and VC-1.
